You have to be carefull with this.
Turning it Off when 99% has it turned On puts you in a significant disadvantage.

dcs500 has like 23.033 kils , he is in the same platoon with me ..

23.033 plus kills arrent a disadvantage hehehe

Yeah, and about 4 million deaths.

On a serious note I've messed around with settings so much I don't really know what good or bad , and BF1 has so many issues now that game settings are, in my opinion, irrelevant, you're basically at the mercy of latency and other players ping.
